EFI: CD devices are not marked as read only

[Jessica Hamilton]

With the EFI Block I/O protocol, code such as blockIo->Media->ReadOnly returns false, which is clearly incorrect.

Example output from my bootloader:

add_boot_device_for_image()
  devicepath type = 3 (MESSAGING_DEVICE_PATH)
  devicepath subtype = 1 (ATAPI_DP)
  media read only = no
  media removable = yes
add_cd_devices()
  devicepath type = 4 (MEDIA_DEVICE_PATH)
  devicepath subtype = 2 (CDROM_DP)
  media read only = no
  media removable = yes
